STOVE.

Specification of Letters Patent No. 5,014, dated March 13, 1847.

To all whom it may concern:

Be it known that we, JOHN' S. MARLL and WILLIAM I. OGDEN, of Georgetown, in the District of Columbia, have invented a new and useful Improvement on Stoves for Heating Apartments, which we call the Hot-Air-Tight Radiator; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same.

The nature of our invention, consists in combining in one stove the application of a peculiar arrangement of the-properties of the three most etficient and approved kinds, viz :the hot-air, air-tight, and radiator; for warming one or many apartments,supplying heat to those below as well as to those above and around, by means of pipes; and by valves or dampers to regulate the warmth in any apartment, or by the same means to cut it off from any apartment; and with the aforesaid advantages, combining that of economy, in cost of the stove over the usual furnaces for heating buildings, and in cost of fuel,consuming, according to the size of the stove, from onehalf to one peck of coal per day.

To enable others skilled in the art, to make and use our invention, we will pro-' ceed to describe its construction and operation.

The main body of the stove and its radiating pipes are constructed of sheet-iron, similar to the common radiator stove, of which, in this instance, for example, we have chosen the elliptical cylindrical form; and within it and attached to the same, of sheetiron, and cast-iron, the various tubes, plates, apartments, valves or dampers, grates and bottoms, as more .fully described in this specification and by the accompanying drawing. V

What we claim as our invention and desire to secure by Letters Patent, is

The arrangement of the hot air chamber. and tubes in combination with the radiating pipes e, e, e, e and division plate .Eqwith its valves, substantially in'the manner de,-- Scrlbed- JOHN s. MARLL. i Witnesses: WILLIAM I. OGDEN.
